-##&lt;iron-icon&gt;
-
-The `iron-icon` element displays an icon. By default an icon renders as a 24px square.
-
-Example using src:
-
-```html
-<iron-icon src="star.png"></iron-icon>
-```
-
-Example setting size to 32px x 32px:
-
-```html
-<iron-icon class="big" src="big_star.png"></iron-icon>
-
-<style is="custom-style">
-  .big {
-    --iron-icon-height: 32px;
-    --iron-icon-width: 32px;
-  }
-</style>
-```
-
-The iron elements include several sets of icons.
-To use the default set of icons, import `iron-icons.html` and use the `icon` attribute to specify an icon:
-
-```html
-<link rel="import" href="/components/iron-icons/iron-icons.html">
-
-<iron-icon icon="menu"></iron-icon>
-```
-
-To use a different built-in set of icons, import the specific `iron-icons/<iconset>-icons.html`, and
-specify the icon as `<iconset>:<icon>`. For example, to use a communication icon, you would
-use:
-
-```html
-<link rel="import" href="/components/iron-icons/communication-icons.html">
-
-<iron-icon icon="communication:email"></iron-icon>
-```
-
-You can also create custom icon sets of bitmap or SVG icons.
-
-Example of using an icon named `cherry` from a custom iconset with the ID `fruit`:
-
-```html
-<iron-icon icon="fruit:cherry"></iron-icon>
-```
-
-See [iron-iconset](iron-iconset) and [iron-iconset-svg](iron-iconset-svg) for more information about
-how to create a custom iconset.
-
-See the [iron-icons demo](iron-icons?view=demo:demo/index.html) to see the icons available
-in the various iconsets.
-
-To load a subset of icons from one of the default `iron-icons` sets, you can
-use the [poly-icon](https://poly-icon.appspot.com/) tool. It allows you
-to select individual icons, and creates an iconset from them that you can
-use directly in your elements.
-
-### Styling
-
-The following custom properties are available for styling:
-
-| Custom property | Description | Default |
-| --- | --- | --- |
-| `--iron-icon-width` | Width of the icon | `24px` |
-| `--iron-icon-height` | Height of the icon | `24px` |
-| `--iron-icon-fill-color` | Fill color of the svg icon | `currentcolor` |
